Yes by all means have a gratitude list, I do and go through it every day
Most people have read or at least heard of the book, The Secret by Rhonda Byrne. I think the basic premise is a fantastic idea, however I believe it leaves out a key ingredient, which without it causes the philosophy to flounder. It's like baking a cake and forgetting to turn on the oven. That key ingredient is, you have to be proactive in getting what you want.
By that I mean go out and drive your life. Yes by all means have a gratitude list, I do and go through it every day, but also go out and put your energy into making it happen.
Think of your life as a bus and you are the driver of that bus. Your hands are on the wheel and your feet are on the pedals. What direction do you think your main focus should be? If you said anything but forward you'd be wrong. Yes you have to look left, right and behind, but primarily you need to be looking forward.
If you're constantly looking back in your life at what has happened to you in the past then you're missing out on the here and now and all the wonderful opportunities that are right in front of you and your bus.
